2i aZZ whom it may concern.

Be it known that 1, WILLIAM J. PAUL, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certaln new and useful Improvements in Coin- Slots, of which the following is a specification. The object of the invention is to provide a coin-slot defining member applicable to and adapted to serve as a filler for the coinreceiving opening in the wall of any of the ordinary types of vending machines, and equipped with detecting and distributing mechanism whereby only coins of the proper denomination are deposited in such a relation to the article delivery mechanism as to permit the operation of the latter.

Further objects and advantages of the invention will appear in the following description of a preferred embodiment, it being understood'that changes in the form,

proportion and minor details may. be resorted to within the scope of the appended claims without departing from the spirit of Inthe drawings,

Figure lis .a front orface view of the device embodying the invention.

Fig. 2 is a side view of the same arranged in operative relation with the coin-receiving opening in the wall of a vending machine.

Fig. 3 is a front view of the device positioned in its proper relation with the casing wall and showing associated therewith escutcheon plates to reinforce the walls of the coin-receiving opening and cooperate with the filler forming an element of the slot defining member. a

Fig. l is a view similar to Fig. 2 including the escutcheon plates.

Arranged in a casing wall 1,- asof the ordinary vending machine, is a coin-receiving opening 2 located above the merchandise delivery mechanism (not shown), so as to other object to the desired position, either to render the delivery mechanismpperative if a coin of the proper denominat on is inserted, or to be segregated and deposited in c any suitable receptacle or, if not a coin of the proper denomination, to be returned to the operator. Disposed in operative relation withsaid coin-receiving opening is a filler 3 having a projecting rounded nose 4 projecting beyond the plane of the outer surface of the casing wall and serving as a means to aid the operator in guiding a coin to the slot or slots 5 in which the coins are to be inserted, the dimensions of the coinslot or slots being such as to determine the value of the coin to be used. Obviously one or two coin-slots may be employed,two beingshown in the drawing, and the outer side of the slot is defined by the wall of the coin-receiving opening which, as illustrated in Figs. 3 and 4, may besupplemented by cured in place by screws 22 or the equivalent thereof.

Leading from the coin entrance opening,

, reinforcing escutcheon plates 20 and 21 se the coin-slot is defined above by a curved wall or rib 6 and below by a rib 6 over which an inserted coin rolls or slides in the act of introducing it into the slot. The rear extremity of said curved wall or rib is provided with a projection or lug 8 disposed between the poles of a magnet 9 of the horseshoe or other suitable type which, as illustrated, may be held in place, in insulated relation with the filler block by a washer 10 secured in place by a screw 11, or the. equivalent thereof, while below and set back somewhat from the forward end of the lower pole of the magnet is a pivotal deflector plate or arm 12. angularly positioned relatively to the said lower pole of the magnet by an adjusting screw 13 mounted in an car 14 or similar support depending from Y the filler block.

gagement) and a flange 16 is extended upward from the filler block to bear, for example, against the inner surface of said casing wall where it may be secured by means of a screw 17 or the like. 1

Obviously the device asdescribed can be applied to any of the ordinary types of vending machines, the same being complete in itself in constituting a filler for the coinrecelving openlng of the casing and as a coin-slot defining means, and also including lmechanism. However, should a coin of a dlfierent denomination be introduced, or

should a slug, blank, or other improper object be inserted in the coin-slot, the effect I of the magnet will be to bring the same into contact with the deflector and releaseit in such a position that it will fall out of alinement with the proper path for operating coins so that it will fail to reach the position required to permit the operation of the delivery mechanism. In the case of a slug or other metallic object of that type, the impulse of the magnet will serve to throw the same against the deflector with such force as to divert it'by reflection into an inoperative position in the casing as, for example, in a suitable receptacle provided for that purpose. Only actual coins of the proper denomination and dimensions will be directed'by the deflector into the path which is necessary to insure deposit in an operative position.

Having described my invention, what I claim is:

l. 'A coin-slot defining attachment for coincontrolled vending machines, having a filler for arrangement in the coin-receiving opening in'the casing of the machine, to define, with reference to a wall of said opening, a slot of dimensions adapted for the receptionof a coin of the required denomina- C1011, and havlng co1n-gu1d1ng means 1n opv erative relation with said slot.

2. A coin-slot defining attachment for com-controlled vending machines, havmg a filler for arrangement in the coin-receiving ing, a slot of'dimensions adapted for the reception of a coin of the required denomination and also having a projecting nose to serve as an exterior coin-directing means, and interior coin-guiding means in communication with the coin-slot.

3. A coin-slot defining attachment for coin-controlled vending machines, having a filler block for arrangement in the coin-receiving opening in the casing of the machine, to define, with reference to a wall of said opening, a slot of dimensions adapted for the reception of a coin of the required denomination, said block being provided with upper and lower flanges for contact with the surface of the wall of the machine and adapted to be secured thereto, and said block also being provided with coin-guiding means in communication with said slot.

4. A coin selecting attachment for coincontrolled vending machines, having a filler for arrangement in the coin-receiving opening in the casing of the machine, and provided with a coin-chute defined by upper and lower guiding means, and detecting and distributing mechanism including a magnet and a deflector, into contact with the latter of which, objects traversing the coin-chute are directed by the magnet.

5. A coin selecting attachment for coincontrolled vending machines, having a filler for arrangement in the coin-receiving opening in the casing of the machine, and providedwith a coin-chute defined by upper and lower guiding means, a magnet in the field of which the coin-chute is arranged and a deflector located in the path of obects traversing the coin-chute under the influence of said magnet.

6. A coin selecting attachment for co1ncontrolled vendlng machines, having a filler for arrangement in the coin-receiving opening in the casing of the machine, and pro vided wlth a coin-chute defined by upper and lower guiding means, a magnet disposed to include said coin-chute in its field to maintain an inserted ob ect in contact with the i upper guiding means, and a deflector disposed in the path of an object traversing the coin-chute under the influence of said magnet.

7. A coin selecting attachment for coincontrolled vending machines, having a filler for arrangement in the coin-receiving open ing in the casing of the machine, and also having a coin-chute defined by uppe' and lower guiding means, the upper guiding means consisting of a rearwardly and downwardly curved wall, a magnet having a projection of said wall arranged between the poles thereof, and a deflector plate dis- I posed below and adjacent to the magnet poles in position for contact with objects traversing the coin-chute under the influence of said magnet.

8. A coin selecting attachment for coincontrolled vending machines, having a filler for arrangement in the coin-receiving opening in the casing of the machine, and also having a coin-chute defined by upper and lower guiding means, the upper guiding means consisting of a rearwardly and downwardly curved wall, a magnet having a projection of said wall arranged between the poles thereof, a deflector plate disposed below and adjacent to the magnet poles in position for contact with objects traversing the coin-chute under the influence of said magnet, and means for varying the angular position of said deflector with reference to 15 the magnet.

In testimony whereof I have afiixed my signature in presence of two Witnesses.
